Thanks so much for the replies. I think we will stick with XP.
We do not have any computer expertise.
David, where did you find that date? I couldn't find it on the MS site.
Our present computer would still work if we didn't need to buy the overly expensive RAM talked about here in another thread.........
Well, I knew about it from reading this stuff on the internet (usually theenquirer.net), but I wanted to verify what I knew before posting it, so I found that same Digg article, but I searched a bit more and also found it on the uSoft web site:

There's a similar page for XP Home and MCE with the same dates. Extended support means security updates, which is fine. On the other hand, mainstream support for XP SP3, which is coming out soon (maybe next quarter, I think?) will also have a 4 - 5 year initial support period and another extended support period, so XP SP3 will probably end up living longer than 2014.
What's the make/model of the computer that needs more memory? Why is it "expensive"? RAM is usually very cheap these days.
I agree that Vista is the downside to buying the XPS 420, but the initial problems that people had with Vista upgrades and drivers won't affect this, since it comes pre-installed with Vista. You might (or might not) have problems finding drivers for older printers, scanners, etc for Vista, but you can check that in advance if you want to try it.
I just bought an XPS m1330 notebook, and I researched it to make sure I could install XP Pro on it before I bought it. There's extensive user support for installing XP Pro on the m1330, and Dell followed up by listing all the drivers and apps for it on their support pages (officially) under XP Pro. Even the media direct thing works if you install it properly. When I looked at the specs for the XPS 420 a few weeks ago, I couldn't find anything similar for it, so I think you would be forced to use Vista on it for now. Plus, I doubt you would want to mess with a clean OS install even if it was available to you.
A week or two after I bought my "refurbished" m1330 (the only thing that seems to make it "refurbished" is a "refurbished" sticker on the bottom of it) they started pushing a sale on it, so if you bought it with the 3 year service/support agreement, it was about the same price as what I paid for mine. I think Dell is trying to push their sales for this quarter, so all these deals might disappear soon.
